Best ResponseYou've already chosen the best response.2This is of the form u/v. (u/v)'=(u'vv'u)/v^2 Here u=x^2 and v=(1+x)^2. (x^n)'=nx^(n1) Can u do it @emcrazy14?

Best ResponseYou've already chosen the best response.0Ok, thanks. Do I multiply (x+1) with a negative sign to change it into (1+x) so that it cancels with the the denominator (1+x)^4?

Best ResponseYou've already chosen the best response.1\[ x^2/(1+x)^2 = 1/(1/x + 1)^2 = ({1 \over x} + 1)^{2}\] use chain rule ... this should be shorter.
